you can have many other cases and forms , but the easiest and most used, both in spoken and written languages, is absolutely :

"così"

3- "in questa via" :
translating "way" you must always consider that "via" in current speaking means "street" , "road" or "away". "Via" can also take different meanings with different prepositions.. (too long for only one post..)
